Abstract

This study evaluated COVID-19 home test kit usability focusing on effectiveness, efficiency, and satisfaction across diverse users and environments. Using a mixed-methods approach-including use analysis, user experience survey (n = 1045), and usability testing (n = 80) in South Korea-we identified a significant gap between high user satisfaction and actual performance. Despite positive satisfaction metrics (SUS score: 74.37 %), we observed concerns regarding effectiveness (29.9 % error rate) and efficiency (20 % unnecessary second kit use, 57.5 % repeated instruction references). The usability of home test kits was significantly influenced by age, education level, and prior experience, while the testing environment showed a less pronounced but still observable effect. Based on our findings, we propose design improvements to instructions, physical components of test kits, and instruction presentation. This research highlights the importance of usability in designing test kits that accommodate diverse populations, potentially improving public health outcomes and pandemic preparedness.

COVID-19家用检测试剂盒的综合混合方法可用性评估：关注有效性、效率和满意度。

本研究评估了COVID-19家用检测试剂盒的可用性，重点关注不同用户和环境的有效性、效率和满意度。使用混合方法——包括使用分析、用户体验调查（n = 1045）和韩国可用性测试（n = 80）——我们确定了高用户满意度和实际性能之间的显著差距。尽管有积极的满意度指标（SUS评分：74.37%），我们观察到对有效性（29.9%错误率）和效率（20%不必要的第二套试剂盒使用，57.5%重复的指导参考）的关注。家庭测试工具的可用性受年龄、教育程度和先前经验的显著影响，而测试环境的影响虽不明显，但仍可观察到。基于我们的发现，我们提出了说明书、测试套件的物理组件和说明书呈现的设计改进。这项研究强调了设计适合不同人群的检测包的可用性的重要性，这可能会改善公共卫生结果和大流行防范。
